After acceptance, evacuate the site and hand over the work ticket to the personnel on duty. The shift leader and the overhaul leader will again carefully inspect the site and check the equipment. After confirming that there is no problem, the person in charge of overhaul will sign the acceptance form together. This is to remove an obstacle and a temporary ground line for power transmission. The operation sequence of disconnecting the temporary wire and sending the power is opposite to the operation sequence of temporary grounding and power failure. After the power is turned on, all hanging signs on the dessert will be cleared to restore the inspection site to the state before the power failure inspection.
